since the shortest lens I've been able to focus on a 4x5 Crown is a 58mm Grandagon.

I'll pic the 2x3. You'll probably have to remove the wire finder up front, since the standard will still be in the body to get any movement at all, but then I'm not sure how much movement the 47 SA has, particulalry if you are shooting the full 2.75x3.25

Oh and if you really meant Graflex body as in SLR and not Graphic as in Speed/Crown, then none of the bodies will work since that mirror gets in the way. In fact, most Graflexes (Series B, D, Super, RB, etc) have a longer than normal lens
